Description

[0001] CROSS-REFERENCE

[0002] This application claims the benefit of U.S. provisional application serial number 62 / 756,552, filed November 6, 2018, which is incorporated by reference in its entirety. BACKGROUND

[0003] Skeletal muscle is the largest organ system in the human body and has two main roles. The first is force generation to make muscles contract, move, and hold posture; the second is glucose, fatty acid, and amino acid metabolism. Skeletal muscle contraction during daily activities and exercise is naturally associated with muscle stress, breakdown, and remodeling, which is essential for muscle adaptation. In individuals with neuromuscular conditions such as Duchenne Muscular Dystrophy (DMD), muscle contraction leads to successive rounds of amplified muscle breakdown that the body struggles to repair. Eventually, as the patient ages, pathophysiological processes develop in the muscle that lead to excessive inflammation, fibrosis, and accumulation of fat deposits, heralding a sharp decline in body function and leading to death.

[0004] DMD is a genetic disease affecting skeletal muscle that is characterized by progressive muscle degeneration and weakness. There remains a need for treatments that reduce muscle breakdown in patients with neuromuscular conditions such as DMD. SUMMARY

[0119] While preferred embodiments of the invention have been shown and described herein, it will be apparent to those skilled in the art that these embodiments are provided by way of example only. Many variations, modifications, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in carrying out the invention. The scope of the invention is intended to be defined by the appended claims, thereby encompassing the methods and structures and their equivalents within the scope of those claims.

[0120] In some respects, this disclosure provides a method for treating neuromuscular diseases by selectively inhibiting skeletal muscle fast-twitch fibromyosin. In particular, the methods of this disclosure can be used to treat DMD and other neuromuscular diseases.

[0121] Skeletal muscle is primarily composed of two types of fibers: slow-twitch fibers (Type I) and fast-twitch fibers (Type II). In each muscle, these two types of fibers are arranged in a mosaic pattern, and the composition varies between different muscles and at different points in growth and development. Slow-twitch fibers have excellent aerobic energy production capacity. They have a low contraction rate but high fatigue tolerance. Slow-twitch fibers typically have higher mitochondrial and myoglobin concentrations than fast-twitch fibers and are surrounded by more capillaries. Due to lower myosin ATPase activity, slow-twitch fibers contract more slowly and produce less energy compared to fast-twitch fibers, but they can maintain contractile function for longer periods, such as in stability, postural control, and endurance training.

[0122] Human fast-twitch muscle fibers can be further divided into two main fiber types (Type Ila, Type IIx / d) based on the specific skeletal muscle fast myosin myosin they express. A third class of fast muscle fibers (Type lib) exists in other mammals, but is rarely found in human muscle. Fast-twitch muscle fibers have superior anaerobic energy production capacity and are capable of generating large amounts of tension in a short period of time. Generally, fast-twitch muscle fibers have lower concentrations of mitochondria, myoglobin, and capillaries than slow-twitch muscle fibers, and thus fatigue more quickly. Fast-twitch muscle fibers produce the strength and faster forces needed to resist activity.

[0123] The proportion of Type I and Type II can vary among different individuals. For example, in a non-athletic individual, each muscle fiber type can comprise nearly 50%. A strength athlete can have a higher proportion of fast-twitch muscle fibers, for example, 70-75% Type II in a sprinter. An endurance athlete can have a higher proportion of slow-twitch muscle fibers, for example, 70-80% slow-twitch muscle fibers in a long-distance runner. The proportion of Type I and Type II fibers can also vary according to the age of the individual. The proportion of Type II fibers, particularly Type IIx, can decrease with age in an individual, leading to loss of lean muscle mass.

[0124] Contraction of skeletal muscle results in muscle damage in subjects with neuromuscular diseases such as DMD, which appears to be more prevalent in fast muscle fibers. It has been observed that in a dystrophic mouse model, acute force loss after a strain injury was greater in a model of fast Type II fiber muscle than in a model of slow Type I fiber muscle (i.e., the soleus muscle). It has also been demonstrated that in a dystrophic mouse model, the degree of acute force loss and histological damage was directly proportional to peak force development during a strain. FIG. 1 Damage from over-contraction is shown, which occurs prior to inflammation and irreversible fibrosis characteristic of late-stage DMD pathology. [Figure adapted from: Claflin and Brooks, Am J Physiol Cell, 2008]. By limiting peak force production of Type II fibers and possibly increasing reliance on healthier Type I fibers, contraction-induced muscle damage in these patients can be reduced. N-benzyl-p-tolylsulfonamide (BTS) is an inhibitor of skeletal muscle fast myosin myosin, which has been shown to protect muscle from pathological muscle disorder in embryos from a DMD zebrafish model. [Source: Li and Arner, PLoS ONE, 2015]. FIG. 2

[0125] ​Skeletal muscle myosin inhibitors that are not selective for Type II fibers can result in undesirable inhibition of skeletal muscle contraction, including respiratory function and undesirable inhibition of heart activity, as the heart shares multiple structural components (e.g., Type I myosin) with skeletal muscle fibers of Type I. While not wishing to be bound by a particular mechanistic theory, the present disclosure provides selective inhibitors of skeletal muscle fast fiber myosin as a therapeutic option for DMD and other neuromuscular diseases. Targeted inhibition of Type II skeletal muscle myosin can reduce skeletal muscle contraction while minimizing impact on a subject’s daily activities.

[0451] Chemical entities having a carbon-carbon double bond or a carbon-nitrogen double bond can exist in Z- or E- (or cis- or trans-) form. In addition, some chemical entities can exist in various tautomeric forms. Unless otherwise specified, compounds described herein are also intended to include all Z-, E-, and tautomeric forms.

[0452] “Tautomer” refers to a molecule in which a proton is mobile from one atom of the molecule to another atom of the same molecule. In certain embodiments, compounds presented herein exist as tautomers. Where tautomerism is possible, a chemical equilibrium of the tautomers will exist. The exact proportions of tautomers depend on several factors, including physical state, temperature, solvent, and pH. Some examples of tautomeric equilibria include:

[0453]

[0454] In some embodiments, the compounds disclosed herein are used in various isotopically-labeled forms, e.g., with 2 H, 3 H, 11 C, 13 C, and / or 14 C content. In one particular embodiment, the compounds are deuterated at at least one position. Such deuterated forms can be prepared by the procedures described in U.S. Patents 5,846,514 and 6,334,997. As described in U.S. Patents 5,846,514 and 6,334,997, deuteration can improve metabolic stability and / or efficacy, thereby increasing the duration of action of a drug.

[0455] Unless otherwise stated, the compounds described herein are intended to include both vaulted and vaulted compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by a 13 C- or 14 C-enriched carbon are within the scope of this disclosure.

[0456] The compounds of the present disclosure optionally contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the compounds can be labeled with isotopes such as deuterium ( 2 H), tritium ( 3 H), iodine-125 ( 125 I), or carbon-14 ( 14 C). Isotopic substitution with 2 H, 11 C, 13 C, 14 C, 15 C, 12 N, 13 N, 15 N, 16 N, 16 O, 17 O, 14 F, 15 F, 16 F, 17 F, 18 F, 33 S, 34 S, 35 S, 36 S, 35 Cl, 37 Cl, 79 Br, 81 Br, 125 I are all contemplated. All isotopic variations of the compounds of the present disclosure, whether radioactive or not, are encompassed within the scope of the present disclosure.

[0457] In certain embodiments, some or all of the compounds disclosed herein 1 H atoms are replaced by 2 H atoms are replaced by deuterium. Methods for the synthesis of deuterium-containing compounds are known in the art, including by way of non-limiting example, the following synthetic methods.

[0458] Deuterium-substituted compounds are synthesized using various methods, such as described in: Dean, Dennis C., ed. Recent Advances in the Synthesis and Applications of Radiolabeled Compounds for Drug Discovery and Development. [In: Curr., Pharm. Des., 2000; 6(10)] 2000, 110 pp; George, W.; Varma, Rajender S. The Synthesis of Radiolabeled Compounds via Organometallic Intermediates, Tetrahedron, 1989, 45(21), 6601-21; and Evans, E. Anthony. Synthesis of radiolabeled compounds, J. Radioanal. Chem., 1981, 64(1-2), 9-32.

[0459] Deuterated starting materials are readily available and subjected to the synthetic methods described herein to provide synthesis of deuterium-containing compounds. A large number of deuterium-containing reagents and building blocks are commercially available from chemical suppliers such as Aldrich Chemical Co.

[0460] The compounds of the present application also include crystalline forms and amorphous forms of these compounds, pharmaceutically acceptable salts, and active metabolites of these compounds having the same type of activity, including, for example, polymorphs, pseudopolymorphs, solvates, hydrates, non-solvated polymorphs (including anhydrates), conformational polymorphs, and amorphous forms of the compounds, and mixtures thereof.

[0461] The present disclosure includes salts of the compounds described herein, particularly pharmaceutically acceptable salts. Compounds of the present disclosure that are sufficiently acidic, sufficiently basic, or both, can react with any of a number of inorganic bases, inorganic and organic acids, and other organic compounds to form a salt. Alternatively, a compound that is inherently charged, such as a compound bearing a quaternary nitrogen, can form a salt with a suitable counterion, such as a halide, e.g., bromide, chloride, or fluoride, particularly bromide.

[0462] In some instances, the compounds described herein can exist in diastereomeric, enantiomeric or other stereoisomeric forms. The compounds presented herein include all diastereomeric, enantiomeric, and epimeric forms as well as appropriate mixtures thereof. Separation of stereoisomers can be achieved by chromatographic methods or by separation of mixtures of diastereomers or enantiomers by recrystallization or chromatography or any combination thereof. (Jean Jacques, Andre Collet, Samuel H. Wilen, "Enantiomers, Racemates and Resolutions", John Wiley And Sons, Inc., 1981, incorporated herein by reference). Stereoisomers can also be obtained by stereoselective synthesis.

[0463] The methods and compositions described herein include the use of amorphous forms as well as crystalline forms (also known as polymorphs). The compounds described herein can be in the form of a pharmaceutically acceptable salt. Likewise, in some embodiments, active metabolites of these compounds having the same type of activity are also included within the scope of the present disclosure. In addition, the compounds described herein can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. The solvated forms of the compounds presented herein are also considered to be disclosed herein.

[0464] In certain embodiments, a compound or salt of a compound can be a prodrug, e.g., where a hydroxyl group in the parent compound is present as an ester or carbonate, or a carboxylic acid present in the parent compound is present as an ester. The term "prodrug" is intended to encompass compounds which, under physiologic conditions, are converted to the drug of the present disclosure. One method for making a prodrug includes one or more selected moieties which are hydrolyzed under physiologic conditions to reveal the desired molecule. In other embodiments, the prodrug is converted by enzymatic activity in the host animal, e.g., by a particular target cell in the host animal. For example, esters or carbonates, e.g., of alcohols or carboxylic acids and esters of phosphates, are preferred prodrugs of the present disclosure.

[0465] Prodrug forms of the compounds described herein, wherein the prodrug is metabolized in vivo to produce a compound set forth herein, are included within the scope of the claims. In some cases, some of the compounds described herein can be prodrugs of another derivative or active compound.

[0466] Prodrugs are generally useful because, in some situations, they can be easier to administer than the parent drug. For example, they can be bioavailable by oral administration whereas the parent is not. Prodrugs can help enhance the cell permeability of a compound relative to the parent drug. Prodrugs can also have improved solubility in pharmaceutical compositions compared to the parent drug. Prodrugs can be designed to be reversible drug derivatives, used as modifiers to enhance the transport of a drug to a site-specific tissue or to increase the residence of a drug within a cell.

[0467] In some embodiments, the design of the prodrug increases the lipophilicity of the agent. In some embodiments, the design of the prodrug increases the effective water solubility. See, e.g., Fedorak et al., Am. J. Physiol., 269:G210-218 (1995); McLoed et al., Gastroenterol, 106:405-413 (1994); Hochhaus et al., Biomed. Chrom., 6:283-286 (1992); J. Larsen and H. Bundgaard, Int.

In some embodiments, a compound or salt of formula (I), (Ia), (Ib), (Ic), (Id), (Ie), (II), (II'), (IIa), (III), or (III') may be administered to the subject prior to mild, moderate, or vigorous activity to reduce or prevent skeletal muscle breakdown due to activity. Moderate to vigorous activity may depend on the subject's ability and may include physical activity that increases the heart rate by at least 20% or more relative to the subject's resting heart rate, such as approximately 50% or more. Examples of moderate to vigorous activity include walking, running, weightlifting, cycling, swimming, hiking, etc.

An inflammatory marker can also be a measure of a condition such as edema, which can be measured using magnetic resonance imaging. The level of an inflammatory marker in the peripheral blood can increase following administration of an inhibitor relative to the pre-treatment level of the inflammatory marker in the subject. Alternatively, the level of an inflammatory marker in the peripheral blood can decrease following administration of an inhibitor relative to the pre-treatment level of the inflammatory marker in the subject.

[0651] Neuromuscular coupling in a subject can be measured before and after administration of a compound or salt of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (IIa), (III), or (III'). Inhibiting skeletal muscle contraction with an inhibitor described herein can not impair neuromuscular transmission, neurotransmitter release, or electrical depolarization of a subject's skeletal muscle. In some cases, inhibiting skeletal muscle contraction can not significantly impair neuromuscular coupling in a subject. As used herein, the word not significantly, with respect to neuromuscular coupling, means less than a 10%, less than an 8%, less than a 6%, less than a 4%, less than a 2%, less than a 1%, less than a 0.5%, or even less than a 0.1% decrease in the level of neuromuscular coupling in a subject relative to the level of neuromuscular coupling in the subject prior to administration of the inhibitor. Neuromuscular coupling in a subject can be assessed by measuring the nerve-induced electrical depolarization of skeletal muscle by using surface or needle electrodes, and recording the electrical activity produced by the skeletal muscle after electrical or voluntary stimulation using electromyography (EMG).

[0652] In some aspects, a method of treating a neuromuscular disease or movement disorder can comprise administering a compound or salt of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (Ila), (III), or (III'), wherein the compound or salt of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (Ila), (III), or (III') can inhibit myosin ATPase activity, native skeletal muscle myofibril ATPase (calcium regulated), or reconstituted S1 with actin, myosin, and troponin. An in vitro assay can be used to test a test compound or inhibitor for effects on myosin ATPase activity. Test compounds can be screened to assess their inhibitory activity on muscle contraction. Inhibitory activity can be determined using a spectrophotometric assay to determine actin-activated ATPase activity. Rabbit muscle myosin subfragment 1 (S1) can be mixed with polymerized actin and dispersed into nucleotide-free assay plate wells. Test compounds can then be added to the wells with a needle array. The reaction can be initiated with MgATP. The amount of ATP consumed in the test vessel over a defined time period can be compared to the amount of ATP consumed in a control vessel. The defined time period can be 5 minutes to 20 minutes. The amount of ATP consumed can be determined by direct or indirect assay. Test compounds that reproducibly and potently inhibit myosin S1 ATPase activity can be further evaluated in a dose response assay to determine the compound's ex vivo IC50 on dissected muscle. The assay can indirectly measure ATPase activity by coupling myosin to pyruvate kinase and lactate dehydrogenase to provide a spectrophotometric detection method at 340 nm based on the conversion of NADH to NAD+ driven by ADP accumulation. In some cases, a test compound can be selected as a compound or salt of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (Ila), (III), or (III') if the ATP consumption in the test vessel is reduced by at least 20% compared to the control vessel. In a kinetic assay, a test compound can be selected when the inhibition of NAD+ generation is enhanced by at least 20%.

[0653] In some cases, the selected inhibitor or test compound can not inhibit cardiac myosin S1 ATPase in an in vitro assay. In some cases, cardiac myosin S1 ATPase or cardiac myofibrils or reconstituted systems can be inhibited by less than 10%, less than 8%, less than 5%, less than 3%, less than 2%, less than 1%, or less than 0.5% when a test compound or a compound or salt of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (Ila), (III), or (III') is tested in an in vitro assay.

The inhibitor compound or salt of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (IIa), (III), or (III') can inhibit contraction of the single skeletal muscle fiber by about 5% to about 90% relative to the value before treatment or untreated control single skeletal muscle. The inhibitor can inhibit contraction of the single skeletal muscle fiber by at least about 5% relative to the value before treatment or untreated control single skeletal muscle fiber. The inhibitor can inhibit contraction of the single skeletal muscle fiber by at most about 90% relative to the value before treatment or untreated control single skeletal muscle fiber. The inhibitor can inhibit contraction of the single skeletal muscle fiber by about 5% to about 10%, about 5% to about 20%, about 5% to about 30%, about 5% to about 40%, about 5% to about 50%, about 5% to about 60%, about 5% to about 70%, about 5% to about 80%, about 5% to about 90%, about 10% to about 20%, about 10% to about 30%, about 10% to about 40%, about 10% to about 50%, about 10% to about 60%, about 10% to about 70%, about 10% to about 80%, about 10% to about 90%, about 20% to about 30%, about 20% to about 40%, about 20% to about 50%, about 20% to about 60%, about 20% to about 70%, about 20% to about 80%, about 20% to about 90%, about 30% to about 40%, about 30% to about 50%, about 30% to about 60%, about 30% to about 70%, about 30% to about 80%, about 30% to about 90%, about 40% to about 50%, about 40% to about 60%, about 40% to about 70%, about 40% to about 80%, about 40% to about 90%, about 50% to about 60%, about 50% to about 70%, about 50% to about 80%, about 50% to about 90%, about 60% to about 70%, about 60% to about 80%, about 60% to about 90%, about 70% to about 80%, about 70% to about 90%, or about 80% to about 90% relative to the ability before treatment or untreated control single skeletal muscle fiber. The inhibitor can inhibit contraction of the single skeletal muscle fiber by about 5%, about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, or about 90% relative to the ability before treatment or untreated control single skeletal muscle fiber.

[0655] The inhibitor compound or salt of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (IIa), (III), or (III') can inhibit contraction of a single skeletal muscle by about 5% to about 90% relative to the value prior to treatment or untreated control single skeletal muscle. The inhibitor can inhibit contraction of a single skeletal muscle by at least about 5% relative to the value prior to treatment or untreated control single skeletal muscle. The inhibitor can inhibit contraction of a single skeletal muscle by at most about 90% relative to the value prior to treatment or untreated control single skeletal muscle. The inhibitor can inhibit contraction of a single skeletal muscle by about 5% to about 10%, about 5% to about 20%, about 5% to about 30%, about 5% to about 40

[0656] about 5% to about 60%, about 5% to about 70%, about 5% to about 80%, about 5% to about 90%, about 10% to about 20%, about 10% to about 30%, about 10% to about 40%, about 10% to about 50%, about 10% to about 60%, about 10% to about 70%, about 10% to about 80%, about 10% to about 90%, about 20% to about 30%, about 20% to about 40%, about 20% to about 50%, about 20% to about 60%, about 20% to about 70%, about 20% to about 80%, about 20% to about 90%, about 30% to about 40%, about 30% to about 50%, about 30% to about 60%, about 30% to about 70%, about 30% to about 80%, about 30% to about 90%, about 40% to about 50%, about 40% to about 60%, about 40% to about 70%, about 40% to about 80%, about 40% to about 90%, about 50% to about 60%, about 50% to about 70%, about 50% to about 80%, about 50% to about 90%, about 60% to about 70%, about 60% to about 80%, about 60% to about 90%, about 70% to about 80%, about 70% to about 90%, or about 80% to about 90% relative to the ability prior to treatment or untreated control single skeletal muscle.

[0657] The effects of a test compound on slow type I skeletal muscle fibers, cardiac muscle bundles, or pulmonary muscle fibers can be assessed. A test compound or inhibitor compound or salt of Formula (I), (la), (lb), (lc), (Id), (le), (II), (II'), (Ila), (III), or (III') can be selected such that it does not significantly modulate the function of slow type I skeletal muscle fibers, cardiac muscle bundles, or pulmonary muscle fibers, and is specific for type II skeletal muscle. As used herein, the term "significantly modulate" can refer to a decrease in the contractile capacity of the muscle of less than 10%, less than 8%, less than 6%, less than 4%, less than 2%, less than 1%, less than 0.5%, or even less than 0.1% relative to the muscle force / contraction prior to inhibitor administration, following inhibitor administration.

[0658] In some aspects, a method of treating a neuromuscular disease or movement disorder can comprise administering to a subject in need thereof a compound or salt of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (Ila), (III), or (III') wherein the compound of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (Ila), (III), or (III') or salt thereof reduces skeletal muscle contraction by 5% to 90% in an ex vivo assay. The ex vivo assay used can be a mouse model. The mouse model used can be a dystrophic mouse model, such as an mdx mouse. The dystrophin gene of the mdx mouse has a point mutation that changes the amino acid encoding glutamine to threonine, resulting in a non-functional dystrophin protein that leads to increased muscle impairment and muscle weakness. The extensor digitorum longus muscle can be dissected from the mdx mouse and mounted on a lever arm. The muscle can be bathed in oxygenated Kreb's solution to maintain muscle function. The test compound or compound or salt of Formula (I), (la), (lb), (Ic), (Id), (Ie), (II), (II'), (Ila), (III), or (III') can be applied to the muscle. An isometric (fixed length) contraction step can then be performed, in which the muscle is stimulated with a series of electrical pulses. A concentric (lengthening) contraction step can be performed, in which the muscle is stretched 10%, 15%, 20%, 25%, or 30% greater than its resting length while at rest or stimulated with electrical pulses. In some embodiments, the concentric contraction step is repeated 2 to 50 times. In some embodiments, the concentric contraction step is repeated 2 to 40 times. In some embodiments, the concentric contraction step is repeated 2 to 30 times. In some embodiments, the concentric contraction step is repeated 2 to 20 times. In some embodiments, the concentric contraction step is repeated 2 to 10 times. In some embodiments, the concentric contraction step is repeated 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 times to cause muscle fiber damage. In some embodiments, the electrical pulses can have a frequency of about 1 Hz to about 500 Hz. In some embodiments, the electrical pulses can have a frequency of about 1 Hz to about 400 Hz. In some embodiments, the electrical pulses can have a frequency of about 1 Hz to about 300 Hz. In some embodiments, the electrical pulses can have a frequency of about 1 Hz to about 200 Hz. In some embodiments, the electrical pulses can have a frequency of about 1 Hz to about 100 Hz. The electrical pulses can have a frequency of about 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, or 150 Hz. The series of electrical pulses can include individual pulses of different frequencies. The time period for each pulse of the series of electrical pulses can be between 0.1 seconds to 0.5 seconds for each pulse.The time of each pulse can be 0.1, 0.2, 0.3, 0.35, 0.4, or 0.5 seconds. Muscle membrane damage can also be measured by incubating the muscle in active orange after isometric or eccentric contractions. Active orange is a fluorescent dye that is taken up by muscle fibers with membrane damage. The number or proportion of dye-positive fibers can then be quantified by histology. A test compound can be selected as a compound or salt of Formula (I), (la), (lb), (lc), (Id), (le), (II), (II'), (Ila), (III), or (III') when the test force drop and / or the proportion of dye-positive fibers is at least 20% less than the control force drop and / or dye uptake.

[0659] Using a set of isometric or eccentric contractions, the force generated by the muscle can be measured. The change in force generated by the muscle before and after a set of isometric or eccentric contractions can be calculated as the test force drop and compared to the change in force generated by muscle contraction from the first pulse to the last pulse in a control sample that was not exposed to the test compound (control force drop). The force drop can be used as a proxy for muscle damage, and a test compound can be selected as an inhibitor compound or salt of Formula (I), (la), (lb), (lc), (Id), (le), (II), (II'), (Ila), (III), or (III') when the test force drop is at least 20% less than the control force drop.

[0680] Combination therapy

[0681] This article also relates to combination therapies, such as the co-administration of the disclosed compounds and additional therapeutic agents as part of a specific treatment regimen designed to provide a beneficial effect from the combined action of these therapeutic agents. The beneficial effect of such combination therapy includes, but is not limited to, the synergistic pharmacokinetic or pharmacodynamic effects resulting from the combination of therapeutic agents. The co-administration of these therapeutic agents is typically carried out over a defined time period (usually hours, days, weeks, months, or years, depending on the chosen combination). Combination therapies are intended to cover the sequential administration of multiple therapeutic agents, i.e., where the various therapeutic agents are administered at different times, and are also intended to cover the administration of these therapeutic agents or at least two therapeutic agents in a substantially simultaneous manner.

[0682] For example, substantially simultaneous administration is achieved by administering to a subject a single formulation or composition (e.g., tablets or capsules of various therapeutic agents in a fixed proportion) or multiple single formulations (e.g., capsules), each of which is administered simultaneously. The sequential or substantially simultaneous administration of the various therapeutic agents is achieved via any suitable route, including but not limited to oral, intravenous, intramuscular, and direct absorption through mucosal tissues. The therapeutic agents are administered via the same route or via different routes. For example, the first therapeutic agent in a selected combination is administered via intravenous injection, while the other therapeutic agents in the combination are administered orally. Alternatively, for example, all therapeutic agents are administered orally, or all therapeutic agents are administered via intravenous injection.

[0683] The components of the combination are administered to the patient simultaneously or sequentially. It should be understood that these components are contained in the same pharmaceutically acceptable carrier and therefore administered simultaneously. Alternatively, the active ingredient is contained in a separate pharmaceutical carrier, such as a conventional oral dosage form, for simultaneous or sequential administration.

[0684] In some embodiments, the compounds or salts of this disclosure may be administered in combination with oral corticosteroids. In some embodiments, the compounds or salts of this disclosure are administered in combination with deflazacort. In some embodiments, the compounds or salts of this disclosure are administered in combination with prednisone. In some embodiments, the compounds or salts of this disclosure are administered in combination with morpholino antisense oligomers. In some embodiments, the compounds or salts of this disclosure are administered in combination with exon skipping therapy. In some embodiments, the additional therapeutic agent is eteplirsen or atalulone.

[0685] In certain embodiments, the compounds or salts of the present disclosure are used in combination with gene therapy. In certain embodiments, the compounds or salts of the present disclosure are used in combination with an adeno-associated virus (AAV) comprising a gene encoding a replacement protein (e.g., dystrophin) or a truncated form thereof (e.g., microdystrophin). In certain embodiments, the compounds or salts of the present disclosure are administered in combination with vamorolone.

[0686] Examples

[0687] The present application will now be generally described with reference to the following examples, which are included for the purpose of illustration only and are not intended to limit the application in any way.

[0688] The following synthetic schemes are provided for illustration and not limitation. The following examples illustrate various methods of preparing the compounds described herein. It will be appreciated that those skilled in the art will be able to prepare these compounds by analogous methods or by making modifications known or to be developed to the methods known to those skilled in the art. It will also be appreciated that those skilled in the art will be able to prepare the compounds of the present disclosure by using appropriate starting materials and modifying the synthetic routes as described below in an analogous manner. In general, the starting materials and reagents can be obtained from commercial suppliers or synthesized or prepared as described herein or known to those skilled in the art.

[0689] Example 1. General Procedure - Synthesis of 2-benzyl-6-(2-(2,2,2- trifluoroethoxy)pyrimidin-5-yl)pyridazin-3(2H)-one

[0690]

[0691] Example 2. Exemplary Procedure - Synthesis of 2-benzyl-6-(2-(2,2,2- trifluoroethoxy)pyrimidin-5-yl)pyridazin-3(2H)-one

[0692]

[0693] The bromofluoropyrimidine is combined with an alcohol (e.g., 2,2,2-trifluoroethanol), cesium carbonate, and an aprotic solvent (e.g., DMF). If necessary, the mixture is gently heated to increase the rate of fluorine displacement. Isolation of the major product provides the corresponding 2-substituted pyrimidine. A Suzuki reaction at the C-4 bromo position using a palladium catalyst (e.g., [l,l-bis(diphenylphosphino)ferrocene]dichloropalladium(II)) and a weak base (e.g., potassium acetate) in dioxane / water gives the biaryl core in good yield. Alkylation of the nitrogen is cleanly performed using various arylmethyl bromides or arylmethyl chlorides (e.g., benzyl chloride) and an inorganic base in a polar aprotic solvent (e.g., DMF). Alternatively, the nitrogen of the pyridinone can be functionalized using the Mitsunobu method. This requires a hydroxymethyl aryl compound (e.g., benzyl alcohol), triphenylphosphine, and a carbodiimide reagent (e.g., DEAD). Both alternatives are used to prepare the desired product depending on the availability of the appropriate coupling partner.

[0694] Examples 1 and 2 can be modified as appropriate to prepare the compounds described in Tables 1 and 2 herein.

[0747] Example 10. Skeletal muscle myofibril ATPase assay

[0748] Overview: Myosin ATPase activity is assessed by using a coupled reaction system in which ADP produced by myosin ATPase function is coupled to the disappearance of NADH by a pyruvate kinase / lactate dehydrogenase (PK-LDH) system. Myosin ATPase activity produces ADP, which is used as a substrate for PK to produce pyruvate and regenerate ATP. Pyruvate is then used as a substrate by LDH to oxidize NADH to NAD+. The rate of the reaction is monitored by the time-dependent disappearance of NADH using absorbance at 340 nm. Inhibition of ATPase activity by the compounds assayed is indicated by a decrease in the rate of NADH loss relative to vehicle-treated controls within the experimental time window. To assess the selectivity of the compounds assayed for skeletal muscle myofibrils, the compounds are counterscreened in cardiac myofibrils.

[0749] Materials: The following stock solutions and reagents are used in the skeletal muscle myofibril ATPase assay:

[0750]

[0751] Stock solution of pCa buffer. Combine PIPES, CaCl2, and EGTA solutions with 70 mL of water. Adjust the pH to 7.0 and adjust the final volume to 100 mL.

[0752]

[0753]

[0754] Buffer A and Buffer B. Buffers were stored on ice until use.

[0755] Buffer Preparation

[0756]

[0757] Skeletal muscle myofibril ATPase assay procedure: BSA, ATP, NADH, PEP, and DTT solutions were thawed at room temperature and then transferred to ice. Myofibrils were frozen pellets were transferred to a tube of sufficient size with approximately twice the desired volume and capped. Myofibrils were thawed by rolling in a water bath at room temperature for about 15 minutes and cooled on ice. Buffer A and B were prepared by adjusting the volume as needed according to the number of wells and stored on ice. 0.5 μL of the compound to be tested was added to the wells. 25 μL of Buffer A was dispensed into the wells, followed by 25 μL of Buffer B. The absorbance of the wells at 340 nm was measured using a kinetic protocol, where the wells were read every 1.5-2 minutes for 45 minutes. The slope of the data was approximated by subtracting the minimum absorbance value from the maximum value for each well. This was done in SoftMax Pro software or a spreadsheet program such as Excel. The data was normalized using GraphPad Prism 8.0 by assigning a value of 100% to the 1% DMSO vehicle well. Typically, the normalized 0% value was simply assigned to the (Max-Min) value 0. The normalized data was fit to a four-parameter Logistic sigmoidal equation with a floor constraint of 0 or greater. The compounds of Tables 1-4 were tested, and the results of the assays are presented in Table 5 herein. A = IC 50 Less than or equal to 10 μM; B = IC 50 Greater than 10 μM and less than 100 μM; C = IC 50 Greater than 100 μM.

[0758] Example 11. Cardiac myofibril ATPase assay

[0759] A counter screen was performed according to Example 10 using frozen myofibril pellets obtained from cardiac tissue. The assay was performed in the same manner as described above, but with the following notable differences: the final well concentration of myofibrils was 1.0 mg / mL, and KCl was omitted from the formulation.

[0760] The compounds of Tables 1-4 were tested, and the results of the assays are presented in Table 6 herein. A = IC 50 Less than or equal to 10 μM; B = IC 50greater than 10 μM and less than 100 μM; C = IC 50 greater than 100 μM; D = IC 50 greater than 60 μM.

[0761] Example 12. Tibialis Anterior Assay

[0762] Duchenne muscular dystrophy (DMD) patients and mdx mice lack dystrophin in their skeletal muscle and are more susceptible to contraction-induced injury than control muscle. The susceptibility of mdx mice to limb muscle injury after administration of the compounds disclosed herein was evaluated using in situ two piece maximally activated tibialis anterior (TA) muscle. A 20% stress segment relative to muscle fiber length was initiated from the plateau of isometric contraction. The degree of injury was assessed one minute later by the deficit in isometric force.

[0763] In situ preparation

[0764] Mice 2-19 months of age were tested. Specific pathogen free (SPF) C57BL controls and mdx mice were either purchased or bred in-house from a mating pair purchased from Jackson Laboratories. All control mice were of the C57BL / 10J strain except for the 19 month old mice which were C57BL / 6. The use of C57BL / 6 mice for the oldest group was necessary because unlike C57BL / 10J mice, C57BL / 6 mice can be purchased from the aging rodent colony maintained by the National Institute on Aging for high age mice.

[0765] Extended retraction protocol

[0766] Mice were initially anesthetized with an intraperitoneal injection of Avertin (tribromoethanol; 13-17 ll / g). Anesthesia was supplemented until no response to tactile stimulation was detected. This level of anesthesia was maintained throughout the experiment using additional doses of Avertin. The tendon of the TA was exposed through an incision at the ankle. The tendon was cut a few millimeters from the end of the muscle. The tendon was tied with 4.0 nylon suture as close to the muscle attachment as possible and the tendon was folded back on itself and tied again. The tendon and exposed muscle were kept moist by periodic application of isotonic saline. The mouse was placed on a heated platform maintained at 37°C. The mouse's foot was secured to the platform with a cloth tape and the knee was secured in a clamp between sharp screws. The tendon of the muscle was securely tied to the lever arm of a servo motor. The servo motor controlled the position of the muscle and monitored the force generated by the muscle. All data were displayed on a digital oscilloscope and stored on a computer.

[0767] The TA muscle was stimulated with 0.2-ms pulses through two needle electrodes that penetrated the skin on either side of the peroneal nerve near the knee. The stimulation voltage and subsequent muscle length (Lo) were adjusted for the maximum isometric twitch force (Pt). While held at Lo, the muscle was stimulated at increasing frequencies from 150 Hz in 50 Hz steps until the maximum force (Po) was reached, typically 250 Hz. A 1- to 2-minute rest period was allowed between each tetanic contraction. Muscle length was measured with a caliper based on well-defined anatomical landmarks near the knee and ankle. The optimal fiber length was determined by multiplying Lo by a TA Lf / Lo ratio of 0.6.

[0768] FIG. 1

[0769] Each muscle was stretched in situ twice, stimulating the muscle at 250 Hz, the frequency most often leading to Po. A protocol consisting of only two contractions was used to avoid fatigue. Stretching started from the plateau of the Lo tetanic contraction. The time course of the protocol is shown in FIGS. 3-6 At time 0, stimulation was started, and the muscle was held motionless for 100 ms to allow maximum activation. From the plateau of the maximum isometric contraction, a length change (LC1) of 20% Lf was applied at a rate of 1 Lf / s. Stimulation was stopped at the end of the stretch ramp. The muscle was held at the stretched length for 100 ms and then returned to Lo at the same rate. The same second lengthened contraction (LC2) as the first was performed 10 minutes later. The maximum isometric force was measured 1 minute later and again every 5 minutes for 15 minutes. Force deficit was calculated as the difference between the isometric force during LC1 and the maximum isometric force measured at any given time and expressed as a percentage of the isometric force during LC1. Recovery within 15 minutes after the two lengthened contraction protocol was quantified as the difference between the isometric force measured at 15 minutes and the isometric force after the second lengthened contraction and expressed as a percentage of the initial Po.

[0770] The experimental protocol included two muscle stretches during maximal activation followed by maximal activation to measure the reduction in maximal isometric force (Po). The change in muscle length is shown relative to the fiber length (Lf) at 20% stress, where 100% corresponds to the optimal muscle length for force development (Lo). The muscle was stretched at a rate of 2 Lf / s. The reduction in Po after the two stretch protocol in a representative mdx mouse is shown. Each lengthened contraction started from the plateau of the maximal isometric contraction. The second lengthened contraction (LC2) occurred 10 minutes after the first lengthened contraction (LC1). The maximal force during the isometric contraction was measured 10 minutes after LC2 (tl min). The force deficit was calculated by dividing the difference between Po during LC1 and Po measured at any time after LC1 by the Po during LC1 and multiplying by 100%. The suture was cut from the muscle and the muscle was weighed. After removal of the TA muscle, the deeply anesthetized mouse was euthanized by inducing a pneumothorax. The total cross-sectional area (CSA) of muscle fibers of the TA muscle was calculated by dividing the muscle mass by the product of Lf and 1.06 mg / mm3(density of mammalian skeletal muscle). The specific Po was calculated by dividing Po by CSA. The results of the test are shown in FIG. 3 .

[0771] FIG. 4 The reduction in force before injury at 100 Hz for compound 5 of the disclosure is shown. Force in the TA muscle of an mdx mouse was measured in situ at 100 Hz before and after oral administration of compound 5. A 100 Hz stimulus was applied every 10 minutes and the change in force was recorded before the start of the centrifugation injury protocol. This measure gives an indication of the relative ability of compound 5 to reduce force in the target tissue.

[0772] FIG. 5 The reduction in force after injury at 175 Hz for compound 5 of the disclosure is shown. The maximal force was measured in situ in the TA muscle at 175 Hz before and 10 minutes after the two rounds of lengthened (lengthened) contractions. In mdx mice, lengthened contractions produce exaggerated force drop. This measure gives an indication of the relative ability of compound 5 to reduce the drop in force after centrifugation contractions. FIG. 6 The intermediate lengthened force drop for compound 5 of the disclosure is shown. The TA muscle was injured in situ by two maximal centrifugation contractions, each 20% lengthened, 10 minutes apart. This indicator measures the relative drop in pre-lengthened force between the first and second contractions.

[0773] FIG. 1 The increase in TA mass after injury for compound 5 of the disclosure is shown.

[0774] Prolonged injury to TA muscle in mdx mice results in a delayed increase in muscle weight after injury. This can be due to fluid accumulation in the form of edema. Muscles were removed from mice (both injured and contralateral) 1 hour after injury and weighed. The relative increase in weight of the injured muscle relative to the contralateral muscle was recorded. A decrease in this relative change indicates a decrease in edema after injury.
